Complete Athlete Evaluation Framework Setup Guide
You're standing in a parent meeting, trying to explain why their athlete didn't make the starting lineup. Your evaluation notes say "good potential, needs work." The parent asks: "What specific criteria? How does she compare to other players?" You don't have clear answers. The meeting becomes defensive.
This scenario repeats itself across coaching staffs everywhere. Coach A focuses on game performance. Coach B emphasizes training effort. Coach C prioritizes technical skills. When team selection meetings arrive, debates replace decisions. Without objective data, every evaluation becomes subjective opinion. Parents question fairness. Coaches spend hours justifying decisions they can't clearly defend.
Research confirms what you already know. A 2022 study on practitioner adherence(opens in new tab) found that 96.1% of practitioners recognize their responsibility for systematic athlete development. Yet monitoring and assessment practices receive the lowest adherence scores. Many rely on subjective "observation" and "coach's eye" due to challenges with structured data collection. A comprehensive 2020 systematic review of talent selection(opens in new tab) reveals that without structured criteria, talent selectors use only 3-5 limited cues and suffer from confirmation bias. They search for information that supports initial impressions rather than objective performance. This results in low inter-judge agreement across evaluators. In contrast, research on mental toughness evaluation(opens in new tab) demonstrates that systematic scoring methods achieve strong inter-rater reliability with an ICC of 0.83 when structured frameworks are implemented.
By the end of this guide, you'll know how to:
- Design systematic evaluation frameworks that reduce subjective bias
- Choose appropriate rating scales backed by research
- Create evaluation criteria that improve inter-rater reliability
- Implement frameworks that save time and reduce parent conflicts
- Build systems that show athlete progress objectively

Why Systematic Evaluation Frameworks Matter
Systematic evaluation frameworks transform subjective coaching decisions into objective, defensible assessments. The benefits appear in three distinct areas: operational improvements through reduced time waste, research validation of structured approaches, and clear business returns through measurable improvements.
The Hidden Costs of Informal Evaluation
Informal evaluation creates costs you see and costs you don't. The visible costs appear in your calendar. You spend hours in defensive meetings with parents. These conversations exhaust everyone because nobody has objective data. Arguments replace discussions.
The invisible costs run deeper. Coach-athlete trust erodes when evaluations feel inconsistent or unfair. Athletes miss development opportunities because unclear feedback doesn't guide improvement. Your coaching staff experiences burnout from constant justification of subjective decisions. Parent relationships suffer permanent damage over perceived unfairness.
Case studies from digital evaluation platforms show 120 hours saved per evaluation cycle. That's time previously spent on data entry that took 8 hours daily for 15 consecutive days. That time now returns to actual coaching.
What Research Shows About Subjective Bias
Human brains create patterns automatically. This helps coaches make quick decisions. But it also introduces systematic errors in athlete evaluation. Research identifies three critical biases that undermine informal assessment methods.
Research on talent identification(opens in new tab) demonstrates that confirmation bias causes evaluators to actively seek, focus on, and recall information that supports their initial impressions. You initially rate Sarah as a top player. Your brain unconsciously looks for evidence confirming this rating. You notice her successful plays more than her mistakes. This continues even when her current performance declines.
Primacy effect means initial impressions dominate decision-making despite subsequent performance changes. Mike makes a strong first impression at tryouts. You rate him higher overall despite inconsistent season performance. That first impression created a mental anchor that's difficult to adjust.
Limited cue usage shows that talent selectors rely on only 3-5 limited cues when evaluating athletes. You might focus mainly on speed and technical skills but overlook tactical awareness and mental resilience. This narrow focus misses comprehensive athlete assessment.
Systematic reviews of talent selection research reveal that accuracy rates for predicting athlete potential remain quite low across evaluators. Low inter-judge agreement becomes the norm without structured criteria.
Structured criteria force evaluation of specific, observable behaviors across all domains separately. This reduces reliance on subjective impressions. A 2023 study on mental toughness assessment(opens in new tab) shows that when coaches implement systematic scoring methods, they achieve ICC values of 0.83. This represents good reliability, showing substantial agreement between evaluators.
The Business Case for Systematic Evaluation
The numbers tell a clear story. Organizations that implement systematic evaluation frameworks experience measurable improvements in key areas. These improvements compound over time.
Coach retention increases when evaluation processes become clear and defensible. Coaches experience less stress from defensive meetings. They spend time coaching instead of justifying subjective decisions. This creates better work environments that reduce turnover.
Parent complaint meetings drop significantly when evaluation criteria become transparent. Parents may disagree with ratings. But they understand how those ratings were determined. The conversation shifts from "this isn't fair" to "here's how she can improve." Organizations consistently report substantial reductions in complaint meetings after implementing structured evaluation.
Professional credibility improves both internally and externally. Your coaching staff appears more organized and systematic. Parents view your program as more professional. This supports program growth through positive reputation and word-of-mouth recommendations.
Systematic evaluation frameworks form the foundation of professional athlete development programs. Learn how Striveon supports systematic athlete development.
Key Takeaways:
- Informal evaluations cost time, trust, and athlete development speed. 96.1% of practitioners recognize systematic evaluation's importance, yet it receives the lowest adherence scores.
- Research proves structured frameworks eliminate cognitive biases. They reduce confirmation bias, primacy effects, and limited cue usage. Coach agreement improves significantly, reaching ICC values of 0.83 with systematic criteria.
- The investment in systematic evaluation pays back immediately. Digital systems save 120 hours per evaluation cycle. More importantly, you make fairer, more defensible decisions that strengthen all relationships.
Designing Your Evaluation Framework: Core Components
Effective evaluation frameworks require three core components working together. You need clear skill categories that cover all aspects of athletic performance. You need rating scales that allow meaningful discrimination between performance levels. You need specific criteria definitions that make each rating level objective and measurable.
The balance matters as much as the components themselves. Your framework must be detailed enough for consistency across coaches. But it must remain simple enough for practical use during actual evaluations. Too complex and coaches won't use it consistently. Too simple and it loses the objectivity you need.
Defining Skill Categories (Technical, Tactical, Physical, Mental)
Research validates the 4-domain approach to athlete evaluation. This framework appears consistently across sports science literature and professional coaching organizations. The approach is comprehensive without becoming overwhelming. It creates natural categories that match how coaches already think about athlete development.
Technical skills cover sport-specific execution. This includes fundamental movement patterns, skill mechanics, and technique quality. In basketball, this means shooting form, dribbling technique, and passing mechanics. In swimming, this covers stroke technique, turns, and starts.
Tactical skills address decision-making and game awareness. This evaluates how athletes read situations, make choices under pressure, and understand strategic concepts. Tactical evaluation asks: Does the athlete position correctly? Do they recognize opportunities? Can they adjust to changing game situations?
Physical skills encompass fitness, strength, speed, and endurance. These qualities support technical and tactical execution. Physical evaluation considers sport-specific demands. A swimmer needs different physical qualities than a basketball player.
Mental skills include focus, resilience, coachability, and attitude. These qualities often separate good athletes from great ones. Mental evaluation examines how athletes respond to challenges, accept coaching, maintain composure under pressure, and demonstrate commitment.
A 2003 study using principal components analysis(opens in new tab) demonstrates that multi-dimensional assessment provides more reliable evaluation than single-factor ratings. The research identified a 5-factor scale as optimal for comprehensive athletic assessment. This validates the 4-domain approach as scientifically sound.
Customize these categories to fit your sport. Swimming might emphasize physical performance more than basketball. Basketball might weight tactical awareness higher than individual sports. The four domains remain constant. Their relative importance adjusts to your sport's specific demands.
Choosing Your Rating Scale
Your rating scale determines how precisely coaches can discriminate between performance levels. Too few levels and you can't capture meaningful differences. Too many levels and coaches struggle to apply criteria consistently.
Research and practical experience suggest 8-12 level scales with written descriptors. This range provides optimal discrimination without overwhelming coaches. You might use a 1-10 numeric scale, a 1-5 scale with half-point increments, or a four-tier descriptive scale with subdivisions.
Written descriptors for each level are critical. Numbers alone don't ensure consistency. Two coaches might interpret "Level 5" differently without clear definitions. Written descriptors create shared understanding. They make rating levels objective and comparable.
Multi-level scales with written descriptors provide optimal discrimination and consistency. Research on rating scale design(opens in new tab) shows that multi-dimensional assessment with clear descriptors is more reliable than single-factor ratings.
Consider your coaching staff's experience level when choosing scale complexity. Less experienced coaches benefit from simpler scales with very specific descriptors. Experienced coaches can handle more nuanced scales. Match the scale to your team's capability.
Creating Clear Criteria Definitions
Each rating level needs specific, observable, measurable criteria. This specificity creates the objectivity you need. Without it, you're back to subjective interpretation.
Bad example: "Level 5: Good technique." This tells coaches nothing actionable. What defines "good" technique? How good? Compared to what standard?
Good example: "Level 5: Executes skill correctly 70% of the time under moderate defensive pressure. Demonstrates tactical awareness in positioning. Maintains technique consistency in training environments." This description is specific, observable, and measurable.
Balance specificity with flexibility. Criteria should be clear enough to be objective. But they must allow room for coaching judgment. You're not creating a formula. You're creating a framework that guides consistent evaluation.
Use this template for criteria definitions:
- Execution accuracy: What percentage or frequency of successful execution?
- Context: Does this occur in training, games, or both? Under what pressure level?
- Consistency: How often is this performance demonstrated?
- Progression indicator: What separates this level from the next higher level?
Test your criteria with real evaluations. Have two coaches independently evaluate the same athlete using your criteria. Do they agree? If not, your criteria need more specificity. Target 75% agreement for good reliability, 85% for excellent reliability.
Many coaches find that digital platforms like Striveon provide pre-built frameworks for these 4 skill domains. You can customize rating scales and criteria definitions without starting from scratch. This saves significant setup time while maintaining research-backed structure. Explore Striveon's customizable evaluation criteria.
Key Takeaways:
- Use 4 skill domains (Technical, Tactical, Physical, Mental) for comprehensive assessment. Research validates multi-dimensional frameworks as more reliable than single-factor evaluation.
- Choose 8-12 rating levels with written descriptors. This range provides optimal discrimination without overwhelming coaches.
- Create specific, observable criteria for each level. Specificity creates the objectivity that makes evaluation consistent across coaches. Test criteria by comparing independent evaluations of the same athletes.
Reducing Subjective Bias and Improving Inter-Rater Reliability
Bias elimination and consistency improvement require intentional training and measurement. Structured criteria provide the foundation. But coaches need training to use those criteria consistently. You also need methods to verify that consistency is actually happening.
Understanding Common Evaluation Biases
Research on coaching bias(opens in new tab) demonstrates that confirmation bias makes you favor previously high-rated athletes. You search for, focus on, and remember information that supports initial impressions. Sarah was a top player last season. You unconsciously look for evidence she's still top-tier even if current performance declined. You notice her successful plays more than her mistakes.
Primacy effect means initial impressions dominate decision-making despite subsequent performance changes. Mike made a strong first impression at tryouts. You rate him higher overall despite inconsistent season performance. That first impression created a mental anchor that's difficult to adjust even with contradictory evidence.
Studies on evaluator behavior(opens in new tab) show that limited cue usage causes evaluators to rely on only 3-5 limited cues. This narrow focus misses comprehensive athlete assessment. You focus mainly on speed and technical skills but overlook tactical awareness and mental resilience. This creates incomplete evaluations that miss critical development areas.
Structured criteria address these biases directly. They force evaluation of specific, observable behaviors across all domains separately. You can't overlook tactical awareness when your evaluation form requires a tactical rating with specific criteria. You can't rely solely on initial impressions when you evaluate specific skills demonstrated over multiple sessions.
Training Your Coaching Staff
Calibration sessions create shared understanding of evaluation criteria. Have all coaches evaluate the same athlete independently using your criteria. Then compare and discuss differences. These discussions reveal where interpretation varies.
Example: Two coaches rate the same athlete's ball control differently. One gives Level 6, the other gives Level 4. The conversation reveals different interpretations of "moderate defensive pressure." Define this more specifically. Document the agreed interpretation. This process strengthens criteria clarity.
Establish anchor examples that represent each rating level clearly. Video clips work especially well. These become reference standards. When coaches question whether performance represents Level 5 or Level 6, they compare to anchor examples. This creates consistency across evaluators and over time.
Schedule regular check-ins to maintain consistency. Monthly reviews of evaluation patterns catch drift before it becomes significant. Compare how different coaches rate similar athletes. Discuss any patterns of divergence. This ongoing calibration maintains inter-rater reliability.
Document edge cases when they arise. Sometimes athletes don't fit criteria neatly. When coaches disagree on edge cases, document the resolution. This creates institutional knowledge that guides future evaluations. Your criteria strengthen through practical application.
Measuring Inter-Rater Reliability
You need methods to verify that your evaluation system works. Inter-rater reliability measures how consistently different coaches apply your criteria. High reliability means your system creates objective evaluations. Low reliability means you still have subjective inconsistency.
Use a simple percentage agreement approach. Have two coaches evaluate 10 athletes on 5 skills. That's 50 total ratings. How many match exactly? How many are within one level? Calculate the percentage. This number tells you if your criteria work.
Target 75% exact agreement for good reliability. Target 85% for excellent reliability. If you're below 75%, your criteria need more specificity. Return to the criteria definitions and add more detail to areas with low agreement.
A 2023 study on inter-rater reliability in coaching(opens in new tab) demonstrates that systematic scoring methods achieve ICC values of 0.83. This represents good reliability showing substantial agreement between evaluators. The research examined mental toughness assessments by head and assistant coaches across four races over three months. The systematic scoring framework created consistent evaluation despite subjective nature of mental qualities.
Track agreement percentages over time. Set explicit goals for your coaching staff. "We want 80% agreement between coaches by end of season" creates accountability and focus. Measure quarterly. Discuss results. Celebrate improvements. Address areas needing work.
Evaluation software can automatically flag when different coaches rate the same athlete significantly differently. This helps you identify where criteria need clarification. It turns consistency measurement into an automatic process rather than manual analysis. See how Striveon tracks inter-rater reliability automatically.
Key Takeaways:
- Structured criteria eliminate confirmation bias and primacy effect. They force evaluation of specific, observable behaviors in each domain separately. This reduces reliance on subjective impressions that create inconsistency.
- Calibration training is essential. Coaches need practice using criteria consistently together. Systematic scoring methods achieve ICC values of 0.83 when properly implemented. This represents strong inter-rater reliability.
- Measure inter-rater reliability to validate your system works. Target 75% agreement for good reliability, 85% for excellent reliability. Track over time to ensure consistency improves.
Implementing Your Framework: Practical Steps
Implementation determines whether your carefully designed framework actually gets used. Perfect criteria help nobody if coaches don't apply them consistently. Successful implementation requires pilot testing, coach buy-in, stakeholder communication, and ongoing iteration.
Pilot Phase: Test Before Full Rollout
Start with one or two teams or age groups. Evaluate 10-15 athletes over 2-4 weeks. This limited scope lets you find problems before they affect your entire organization. Small-scale testing is cheaper than large-scale failure.
Gather specific coach feedback. Ask targeted questions. What's unclear in the criteria? What feels too complicated? What's missing? What takes too long? Real-world use reveals issues that theory doesn't.
Refine criteria based on actual experience. Coaches will discover that some criteria work perfectly. Others need adjustment. Some rating levels need more specific description. Some skill categories need different weighting. Practical application shows what needs fixing.
Measure time investment during pilot phase. Compare evaluation time using your new framework versus your old method. If the new method takes significantly longer, consider simplification. If it saves time, quantify that savings. This data helps with coach buy-in later.
Don't skip pilot testing. The time invested here saves much more time later. It prevents organization-wide confusion and frustration. It builds confidence in the framework through demonstrated success.
Getting Coach Buy-In
Involve coaches in framework design from the start. Don't create a system in isolation and mandate its use. Coaches who help build the framework understand it better and own its success. They become advocates rather than resisters.
Address the "this is extra work" concern directly. Show research on time savings. Digital evaluation platforms have documented 120 hours saved per evaluation cycle. That's real time returned to coaching. But acknowledge that initial setup requires investment. Be honest about short-term costs and long-term benefits.
Emphasize benefits that matter to coaches. Fair evaluations reduce stress from parent meetings. Fewer defensive conversations create better work environments. Professional credibility improves. Systematic evaluation makes coaching easier once implemented.
A 2022 study on long-term athlete development practices(opens in new tab) shows that 96.1% of practitioners recognize the importance of systematic development. Yet they struggle without frameworks. Many rely on subjective observation because they lack better tools. Your framework solves this recognized problem. Frame it as support, not burden.
Provide training and ongoing support. Schedule calibration sessions. Offer regular check-ins. Make help easily accessible. Coaches need to feel supported through the transition. Their early success builds momentum for full adoption.
Communicating Criteria to Athletes and Parents
Transparency builds trust more effectively than any other approach. Publish your evaluation criteria openly. Explain what each rating level means. Show what's required for progression. This removes mystery from the evaluation process.
Frame criteria as development roadmaps rather than judgment systems. The message isn't "you're a Level 5." The message is "you're a Level 5, here's what Level 6 looks like, and here's how to get there." This creates motivation rather than discouragement.
Example communication to athletes: "Level 5 in Ball Control means you maintain possession under moderate pressure 70% of the time. Level 6 requires 80% success under high pressure. Here are specific drills that develop this skill. Here's how we'll measure your progress."
Positive Coaching Alliance approach emphasizes focusing on growth mindset and improvement opportunities. Evaluation should support development, not create fixed ability labels. Your communication should consistently emphasize progression and growth potential.
Transparent criteria dramatically reduce parent complaints. Parents may disagree with a rating. But they understand how it was determined. They know what improvement requires. The conversation becomes collaborative problem-solving rather than defensive argument.
Iterating Your Framework
Plan annual reviews of your evaluation framework. Ask: Does our criteria still fit our program goals? Have our athletes' development needs changed? Have coaching methods evolved? Has new research emerged that should inform our approach?
Update based on multiple inputs. Coach feedback reveals practical issues. Athlete development trends show what's working and what isn't. Sport rule changes might require criteria adjustment. New research provides better evidence for specific approaches.
Document all changes clearly. Communicate updates to all stakeholders. Explain why changes were made. This maintains transparency and trust. It also prevents confusion about which version of criteria applies to which evaluation period.
Keep historical data consistent when you change scales. If you modify rating scales, document the change date clearly. Note how new scale correlates to old scale. This maintains longitudinal tracking capability. You can still show athlete progress across scale changes.
Digital vs. Manual Implementation
Manual implementation uses clipboard or paper forms for evaluation. You compile data in spreadsheets. You create charts manually. This approach has low initial costs. No technology learning curve exists. But it's time-consuming, error-prone, and difficult for longitudinal tracking.
Digital implementation uses evaluation software with structured frameworks. This provides automatic calculations, progress tracking, and consistency enforcement. Learning curve exists. Subscription costs apply. But time savings are substantial after initial setup.
Case studies on evaluation platform efficiency show digital systems save significant time. One documented case study found 120 hours saved per evaluation cycle. Data entry that previously took 8 hours daily for 15 days became minimal time with automation. That's real hours returned to coaching.
Consider your organization's size and resources. Small programs with limited budgets might start manual. Large programs with multiple teams benefit more from digital systems. The crossover point is around 5-8 teams. Beyond that scale, manual systems become impractical.
Many coaches find that digital evaluation platforms save 4-6 hours weekly after initial setup. They automate calculations, progress tracking, and parent communication. Platforms like Striveon provide pre-built frameworks that you can customize rather than building from scratch. This speeds implementation while maintaining research-backed structure. Discover Striveon's complete athlete development solution.
Key Takeaways:
- Pilot test with small groups before full rollout. Test with one team, refine based on coach feedback, then scale to full program. This prevents organization-wide confusion.
- Involve coaches in design to ensure buy-in and practical usability. 96.1% of practitioners recognize systematic evaluation's importance but struggle without good frameworks. Your framework solves this recognized problem.
- Publish criteria openly to athletes and parents. Transparency builds trust and reduces complaints. Frame evaluation as development roadmaps that show clear paths to improvement.
- Digital systems save significant time after initial setup. One documented case saved 120 hours per evaluation cycle through automation. Consider digital implementation for programs with 5+ teams.
Measuring Success: How to Know Your Framework Is Working
Success measurement validates your implementation effort. It shows what's working and what needs adjustment. Without measurement, you're operating on assumptions. With measurement, you make data-driven improvements.
Quantitative Metrics
Inter-rater reliability should be your primary success metric. Target 75% exact agreement between coaches for good reliability. Target 85% for excellent reliability. This measures whether your framework creates consistent evaluation across different evaluators.
Calculate reliability quarterly. Have coaches evaluate the same athletes independently. Compare results. Track improvement over time. Set explicit goals and measure progress toward them.
Time savings provide another clear success indicator. Track hours spent in evaluation meetings before and after implementation. Track time spent in parent discussions about evaluation fairness. Target 50% reduction in these time commitments.
One case study documented 120 hours saved per evaluation cycle with digital systems. That's substantial time returned to actual coaching. Even manual systems should show some time savings from reduced defensive meetings and clearer decision-making.
Parent complaints about evaluation fairness should decrease significantly. Count complaints before implementation. Count them afterward. Target 70% reduction in complaints related to evaluation fairness. Transparent criteria reduce perception of unfairness even when parents disagree with ratings.
Qualitative Indicators
Coaches should feel more confident in selection decisions. This confidence shows in their ability to explain decisions clearly. It appears in reduced stress about evaluation processes. Survey your coaching staff regularly. Ask if they feel the framework helps them make better decisions.
Athletes should understand development pathways more clearly. They should know where they are, where they can go, and how to get there. This clarity appears in athlete goal-setting behavior. Athletes with clear criteria set more specific and achievable goals.
Parent conversations should shift from defensive to collaborative. Instead of arguing about fairness, you discuss development strategies. Instead of justifying ratings, you explain pathways to improvement. This shift in conversation quality indicates system success.
Assistant coaches should use criteria consistently without constant guidance. Initially, they need frequent support and clarification. Over time, they should apply criteria independently. This increasing independence shows that criteria are clear and usable.
Athlete Development Outcomes
Athletes demonstrate clearer goal-setting behavior when evaluation criteria are transparent. They know exactly what improvement means. They can track their own progress against clear standards. This creates more effective development planning.
Retention rates often improve when athletes understand development pathways. Athletes stay in programs longer when they see clear paths to improvement. Systematic evaluation provides this clarity. Retention improvements validate that your framework supports athlete development effectively.
Systematic evaluation supports faster skill acquisition by providing specific, actionable feedback. Athletes know precisely what to work on. Coaches provide targeted guidance based on clear criteria. This specificity accelerates improvement more than vague feedback.
Key Takeaways:
- Measure success objectively with quantitative metrics. Track inter-rater reliability (target 75% for good, 85% for excellent). Monitor time savings (target 50% reduction in evaluation meetings). Count parent complaints (target 70% reduction).
- Look for qualitative indicators that show system adoption. Coaches should feel more confident. Athletes should understand development paths clearly. Conversations should become collaborative rather than defensive.
- Ultimate validation comes from athlete development outcomes. Retention rates improve when paths to improvement are clear. Skill acquisition accelerates with specific, actionable feedback from systematic evaluation.
Conclusion
Systematic evaluation frameworks eliminate the cognitive biases that undermine fair athlete assessment. Research proves that structured criteria reduce confirmation bias, primacy effects, and limited cue usage. Coach agreement improves significantly, achieving ICC values of 0.83 with proper implementation. This represents strong inter-rater reliability between evaluators.
The 4-domain framework (Technical, Tactical, Physical, Mental) with 8-12 rating levels provides optimal assessment design. Multi-dimensional assessment is more reliable than single-factor evaluation. Written descriptors for each level create shared understanding across coaches. Specific, observable criteria make ratings objective rather than subjective.
Successful implementation requires pilot testing with small groups before full rollout. Involve coaches in framework design to ensure practical usability and strong buy-in. Publish criteria openly to athletes and parents. Transparency builds trust and dramatically reduces complaints about fairness.
Digital systems save significant time after initial setup. One documented case saved 120 hours per evaluation cycle through automated calculations and progress tracking. For programs with 5+ teams, digital implementation provides substantial efficiency gains.
Measure success through inter-rater reliability (target 75% for good, 85% for excellent), time savings (target 50% reduction), and athlete development outcomes. The framework works when evaluation conversations shift from defensive to collaborative. When athletes understand clear paths to improvement. When coaches make decisions confidently with data rather than opinion.
Next Steps
Start building your framework:
- Define your 4 skill domains and choose a rating scale. Research suggests 8-12 levels with written descriptors.
- Run a calibration session with your coaching staff. Evaluate 3 athletes independently, then compare and discuss differences. This reveals where criteria need clarification.
- Pilot test your framework with 1 team for 2-4 weeks before full rollout. Refine based on real-world feedback, then scale to your entire program.
